I'm lowering the severity to minor, because in my opinion this doesn't
impose a significant impact on wpa_cli's usability.

This is caused by switching wpa_cli to the new (since 1.0~) internal
readline replacement, which might not have all the bells and whistles
GNU readline has to offer, yet(?). You can confirm this by rebuilding
wpa with this patch:

So far this seems to be the only side effect of switching to
WPA_CLI_EDIT (personally I didn't even notice that yet), and abandoning
readline usage is wanted for licensing reasons (especially looking at
the wpa 2.x branch and readline6/ GPL-3). With a little luck, this
feature may get added to future upstream versions, as there seems to be
some rudimentary ctrl-L handling already. In which case we'd consider
backporting it to wpa - although likely not for wheezy.
As we want/ need to avoid depending on GNU readline, I may tag this bug
as wontfix for the time being. Although I certainly hope that wpa_cli's
internal readline implementation gains feature parity with GNU
readline in the externally visible regards.
